The present invention relates to new and useful improvements in drillpress vises embodying means for holding the work to be drilledl rmlywithout the tedious use of jigs, clamps and similar devices.

An important object of the present invention is to provide a vise ofthis character embodying coacting jaws movable relative to each other byindividual jack screws by means of which either of the jaws may beactuated while the other jaw remains stationary, or by means of whichboth of the jaws may be simultaneously actuated.

A further object of the invention is to provide means for swingablymounting the jaws about a vertical axis in order to facilitate theoperation of the vertical spindle of a drill press in drilling longmaterial held in clamping engagement by the jaws.

A still further object of the invention is to provide a device of thischaracter of simple and practical construction, which is efllcient andreliable in use, relatively inexpensive to manufacture and otherwisewell adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a top plan View.

Figure 2 is a side elevational view.

Figure 3 is a fragmentary longitudinal sectional View takensubstantially on a line 3-3 of Figure 1.

Figure 4 is a fragmentary top plan view of the base for the vise.

Figures 5, 6, and '7 are transverse sectional views taken respectivelyon the line 5-5, 6--6 and 1 1 of Figure 3.

Figure 8 is a top plan view of one of the sliding bars carrying the visejaws.

Figure 9 is a bottom plan view thereof, and

Figure 10 is a bottom plan view of one of the Jaws.

Referring now to the drawings in detail wherein for the purpose ofillustration I have disclosed a preferred embodiment of the inventionthe numeral 5 designates a base generally which includes a centrallongitudinally extending bar E and having wings I projecting laterallyat opposite sides of the intermediate portion of the bar, each of thewings being formed with longitudinally extending portions 8 spaced fromthe adjacent sides of the bar 6. The wings 1 and ex- 1 claim. (c1. 4sii-33) j tensionsl 8 form base plates in the plane of the i. fi

bar 6 and having downwardly extending longitudinal and transversereinforcing ribs 9 and I0 on the underside thereof for supporting thebase on the surface of a drill Dress. f

Lugs II are formed onA the underside of the wings 'I to receive bolts orthe like I2 by which the base may be attached to said drill press.

Eachend of the bar 6 is formed with a longitudinally extendingT-slot I3and an intersecting transversely extendingkeyway slot I4. The side edgesof the bar 6 are formed with longitudinally extending grooves I5.v l fAn internally threaded collar I6 is formed with a downwardly extendingT-shaped extension I1 slidably mounted in the T-slot I3 and retainedtherein by a key I8 in the slot I4. See Figures 3 and 6.

A screw I9 is threaded through the collar I6 and is provided with a headat its outer end through which a crank handle 2l extends transverselyand is secured in adjusted position by means of a set screw 22.

A sliding bar 23 is formed with inner and outer end walls 24 and 25 andrecessed at its underside to form a longitudinally extending groove 26for receiving the screw I9. See Figures 8 and 9. The outer end wall 2-5is held slidably engaged to a flange 21 on the head 20 of the screw I9by means of screws or the like 28 and a shoe 28. See Figure 3. One ofthe sliding bars 23 is provided for each end of the bar 6 and eachsliding bar is moved longitudinally at the respective ends of the bar 6by means of the screw I9 and handle 2|, the screw traveling in thestationary collar I6.

The side edges of the sliding bar 23 adjacent its inner end are formedwith inturned flanges 29 slidably mounted in the grooves I5 at the sidesof the bar 6.

The inner end of the sliding bar 23 is curved as indicated at 30 and isformed with kerf 3l at its lower portion in which a correspondinglycurved rib 32, Figure 10, on the lower inner edge of a jaw 33 is seatedfor horizontal swinging movement of the jaw at the inner end of thesliding bar 23.

A plate 34 extends rearwardly from the upper portion of the jaw havingan arcuate slot 35 formed therein for receiving an upstanding stud 36threaded in the top of the bar 23 adjacent its inner end. A clamping nut31 is threaded on the upper end of the stud 36, the nut having a crossbar 38 extending therethrough for threading the .nut downwardly to clampthe plate 34 in its swingably adjusted position on top of the slidingbar 23. Accordingly, the jaws 33 at the inner ends of the respectivebars 23 may be swung about a vertical axis on the upper surface of thebase 5 to clamp therebetween work positioned at an angle on the table ofa drill press.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary. f

It is to -be understood, however, that eve though there is herein shownand described a preferred embodiment of the invention it is to beunderstood that minor changes in the details of construction,combination and arrangement of parts may be resorted to `withoutdeparting from the spirit and scope of the invention as claimed.

is.. Y

A vise of the class described comprising a base including a bar., `wingsprojecting laterally from the center of the bar at each .side thereof,longitudinal extensions on the wings spaced from the sides off the bar,said bar having longttudinal grooves at each side .and at each end andtransverse grooves communicating with" said end grooves,V a slide barvmounted for longitudinal movement on each end of the base bar, inturnedflanges on the slide bars .sliclably received `in said Having describedthe invention, what I claim.

longitudinal side grooves, a threaded guide carried at each end of thebase bar in said longitudinal end Igrooves, each threaded guide beingsecured by a key positioned in said transverse grooves, a jack screwthreaded in each guide and attached to an adjacent slide bar, means formanipulating the screws, and a vise jaw at the inner end of each slidingbar.
